The Ferrari 458....

Post by DSRL McDuff on Wed Jul 26, 2017 3:50 pm



Specification

In Ferrari's first official announcement of the car, 458 was described as the successor to the F430 but arising from an entirely new design, incorporating technologies developed from the company's experience in Formula 1.[6]

The body computer system was developed by Magneti Marelli Automotive Lighting.

Engine
The 458 is powered by a 4,499 cc (274.5 cu in) V8 engine of the "Ferrari/Maserati" F136 engine family, producing 570 PS (419 kW; 562 hp) at 9,000 rpm (redline) and 540 N·m (398 lb·ft) at 6,000 rpm[7] with 80% torque available at 3,250 rpm.[6] The engine features direct fuel injection, which is a first for Ferrari mid-engine setups in its road cars.[6]

Transmission
The only transmission available on the 458 is a dual-clutch 7-speed Getrag gearbox, in a different state of tune shared with the Mercedes-Benz SLS AMG.[6] There is no traditional manual option, making this the fourth road-car after the Enzo, Challenge Stradale and 430 Scuderia not to be offered with Ferrari's classic gated manual. It is the first mainstream model to not be offered with a manual transmission.

Handling

Ferrari 458 Italia (Monaco)
The car's suspension features double wishbones at the front and a multi-link setup at the rear, coupled with E-Diff and F1-Trac traction control systems, designed to improve the car's cornering and longitudinal acceleration by 32% when compared with its predecessors.[6]

The brakes include a prefill function whereby the pistons in the calipers move the pads into contact with the discs on lift off to minimize delay in the brakes being applied.[8] This combined with the ABS and standard Carbon Ceramic brakes have caused a reduction in stopping distance from 100–0 km/h (62-0 mph) to 32.5 metres (107 ft).[9] Tests have shown the car will stop from 100 km/h (62.1 mph) in 90 feet (27 m) or in 85 feet (26 m) with run flat tires, 85 feet (26 m) from 60 mph (97 km/h) and 80 feet (24 m) from 60 mph (97 km/h) with run flat tires.

The adaptive magnetorheological dampers are co-developed with BWI Group.

Performance

Ferrari's official 0–100 km/h (62 mph) acceleration is 2.9–3.0 seconds.[10] The top speed is 340 km/h (210 mph).[11] It has fuel consumption in combined cycle (ECE+EUDC) of 13.3 L/100 km (21.2 mpg‑imp; 17.7 mpg‑US) while producing 307 g/km of CO2.[12]

Ferrari 458 Italia has a power to weight ratio of 2.61 kg (5.75 lb) per horsepower.


458 Italia GT2
Ferrari unveiled their new GTE class racer in 2011 to take part in Championships sanctioned by ACO and FIA. The 458 Italia GT2 drops the "flex splitter" found in the road cars and replaced with a more conventional inlet, with the air exit out through louvers in the bonnet. Under new restrictor regulations, the 4.5L engine produces 464 hp (346 kW; 470 PS), which is less than the road car and the 458 Challenge. Unlike the road car, which has a high-revving low-torque engine, the GT2 version only revs to 6,250 rpm, but maintains a close-to-stock torque number even with the horsepower loss. The double-clutch gearbox had to be replaced, but paddle-shifting is retained since rules in 2011 allow them.

So far the 458 Italia GT2 has had an impressive racing record. The car won the 2012 and 2014 24 Hours of Le Mans, the 2012 12 Hours of Sebring and two editions of the Petit Le Mans, the first in 2011 and the second in 2012.

In 2011 the 458 Italia GT2 took the Intercontinental Le Mans Cup GTE Manufacturers' and the GTE PRO Team Titles, the Le Mans Series GTE Manufacturers' and GTE PRO Team and Drivers' honours and the International GT Open Overall and Super GT Team and Drivers' crowns. The following year, with the creation of an FIA-managed World Championship, the car obtained the GTE Manufacturers' and GTE PRO Team Titles in the FIA World Endurance Championship. In the same year the Italian car gained the European Le Mans Series GTE PRO Team and Drivers' honours and the International GT Open Overall and Super GT Manufacturers', Team and Drivers' crowns. In 2013 the car repeated its successes, winning the FIA World Endurance Championship GTE Manufacturers', GTE PRO Team, GTE Drivers' and GTE AM Team Titles, the European Le Mans Series GTE Team and Drivers' honours, the Asian Le Mans Series GTE Team and Drivers' crowns and the International GT Open Overall and Super GT Manufacturers' and Drivers' Titles. In 2014 the 458 Italia GT2 achieved, for the third straight year, the FIA World Endurance Championship GTE Manufacturers' and GTE PRO Team honours, as well as, for the second time in a row, the GTE Drivers' crown (which had been instituted in 2013). For the fourth time the car also clinched the European Le Mans Series GTE Team and Drivers' Titles, but it didn't take part in the International GT Open and Asian Le Mans Series Championships (the 458 Italia GT3 raced in both these series that year).

In 2015 Ferrari 458 Italia GT2 cars competed in the FIA World Endurance Championship, European Le Mans Series and Tudor United SportsCar Championship.[43]

The car was replaced for 2016 by the Ferrari 488 GTE.
